GREASE-Gill.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed December 6, 1917. Serial No. 205,807.

To all whom it may concern Be it known that I, HENRY N. Felon, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Grease-Cups, of which the following is a specliication.

My invention relates to grease cups, more construction and highly efficient in Opera tion. A further object of my invention is to provide a grease cup with a cap that may be thrust into position'with respect to the body of the cup, and a still further ob1ect is to provide automatic locking means for the cap when the latter is thrust into place; such locking means being disposed between the cup and the cap and wholly concealed by the latter. V

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a perspective view of my improve grease cup showing the parts of the same detached.

Fig. 2-, is a sectional view of the same, and

Figs. 3 and 4, are fragmentary sectional views illustrating modified constructions within the scope of my invention.

My improved grease cup comprises a cup proper having a body 1 and a threaded end 2 whereby it may be secured in its place of use, with an internal chamber 3 receiving the grease. A shown in Fig. 1, the body is grooved at 4 near its upper edge for the reception of a-spring locking ring 5, which serves as the means for retaining the cap 6 in place; the latter being grooved at 7 on its inner wall to provide a shoulder 8 so that when it is set in place the spring ring 5 will engage said shoulder 8 of the cap, as clearly shown in Fig. 2.

The body is provided with a flange 9, and the end of the wall of the cap preferably ongages the top of this flange, as indicated in Fig. 2. The inner edge of this wall be beveled, as indicated at 10, forming a little pocket 11 adjacent the flange 9 which serves to catch any dirt and dust that may collect on the exterior of the body, 1, of the cup and that finds its Way past the end of the flange, 9 and prevent the same passing up the outer wall of the body inside the cap;

and gaining access to the body of grease within the latter. The fit between the cap and body should be quite close, but at the same time a proper working fit so that no difficulty will be had in assembling the parts. To facilitate setting the chambered body 1 in position, the upper edge of the same may be notched, as indicated at 12, for engagement by a screw driver or other suitable form of setting tool. r

In lieu of having the cup body 1' carry the spring locking ring, it may be carried by the cap, as shown in Fig. 3; in which case the body of the cap near the upper wall of the same will be thickened as at 6 and grooved at 7 to receive a spring looking ring 5*. The cup body will have the same groove 4:, as indicated in Figs. 1 and 2. with which the spring locking ring 5 will engage when the cap is thrust into place. Another arrangementwithin the scope of my invention is shown in Fig. 4, where the cup 1 is provided with a groove 4: near the base of the same to receive the spring locking ring 5; the cap 6 in such case being provided with a groove 7 and shoulder 8*, of the character shOWn in Figs. 1 and 2, but disposed nearer the beveled edge 10 thereof.

In all instances the retaining means for the cap are disposed between the cup body and the cap and are wholly concealed by the latter. In some'instances, it may be desirable to combine the modifications illustrated inFigs. 3 and 4, in a structure in which the cap carries the locking ring, as in Fig. 3, but disposed near its beveled edge, as in Fig. 4.

- The spring ring is, of course, a split structure, and I prefer a lapped joint 13, in which the meeting faces of the lapping parts are in the axial plane of the ring body. This ring is designed to provide a close fit between the walls of the parts of the structure at its point of application thereto in the manner of a piston ring whereby it may act as a perfect closure to prevent any access ofdirt or dust, on'the one hand, or grease passing down the walls of the cup, on the other hand when the filled cap is applied to the cup. It is therefore essential that the faces of the lapping parts of the ring shall be in a plane coincident with its point of contact with the. wall of the body or the cap,

as the case may be, to insure a perfectclosure.

The parts of the structure may be cast and shaped in any usual way, or the body may be cast and the cap made of sheet metal spuninto shape, or both parts may be of pressed metal. In practice, the cap is filled with grease and then placed over and pressed down upon the body of the cup, which act will cause the full charge of grease to enter the chamber of the cup by a single push of the-cap; forcing out any grease that may be present therein and driving it to the proper point for distribution. Further flow of grease is by gravity in the usual manner.

While I have referred to a grease cup in describing my improved structure, it will be understood that the improvements constituting my invention may be employed in connection with oil cups; hence the term grease cup in the claims is to be construed as broad enough to cover an oil cup or a grease cup or, in fact, any cupor equivalent structure designed to carry a body of lubricating material and having the features constituting my invention.

I claim:

1. The combination in a grease cup, of a body having an open top and having a groove in its outer wall, a cap closely fitting the body and designed to force a full charge of grease into the cup at one operation, said cap having a groove in its inner wall, and a spring ring carried by the body and adapted 'to engage the groove of the cap to lock the cap in place, said body and cap telescopically fitting and said body having an exterior flange opposing the lower edge of the cap and against which the said edge of the cap is designed to seat when forcing the full charge of grease into the cup.

2. The combination, in a grease cup, of a body open at the top and having a groove in its inner wall adjacent the top thereof, a

cap fitting the body and having a groove in 7 its innerwall, and a springring carried by the body and adapted to engage the groove of the cap whereby the latter may be locked in place, said body and cap telescopically fitting one within the other and said cap adapted to force a full charge of grease into the cup at one operation, said springserving as a scraper to clean the inner wall of the cap during the telescopic movement of the latter.

3. The combination, in a grease cup, of a chambered body having a threaded end, a

' flange adjacent the threaded end; said body having a groove in its outer wall, a cap fitting the body and having a groove in its Copies of this patent may be obtained for inner wall, and a spring ring carried by the structure and engaging said grooves whereby the cap may be locked in place; said cap having an interior beveled wall, and the bottom edge of the cap adjacent said beveled wall being adapted to engage the flange of the chambered body.

at. The combination, in a grease cup, of a chambered body having a threaded end, a flange adjacent the threaded end; said body having a groove in its outer wall adjacent the top of the same, a cap fitting the body and having a groove in its inner wall, and a spring ring carried by the structure and en gaging said grooves whereby the cap may the flange of the chambered body, and the spring ring having a lapped joint with the plane of contact with the engaging wall.

6. In a grease cup, a body recessed to receive grease, a cap closely fitting the same and telescopically movable with respect to the recessed body; said cap adapted to force a. full charge of grease into the recessed body at one operation; the meeting walls of said members being plain surfaced for the greater portion of their extent and'having registering recesses, and a spring ring carried by one of said members and contacting with the other when the cap is forced into place; said ring occupying both of the recesses and locking the members together when the cap is in place. e

. 7. The combination, in a grease cup, of a chambered body having a groove in its meeting faces of the lapping parts in the v outer wall, a cap telescopically'fitting the 1 chambered body and having a groove in its inner wall, and a spring ring carried by one of said. members and contacting with the groove of the other when the cap is forced into place and locking. said members together; said spring ring having 'a lapped U joint with the meeting faces of the lapping HENRY N.
